The primary outcome was determined by assessment of survival and incidence of BPD,which was defined by the need for supplemental oxygen at 36 weeks gestational age (GA); an infant who was alive without BPD at 36 weeks GA was counted as success; an infant who died or had BPD at 36 weeks GA was counted as a failure.

Official Title ICMJE

The Effects of Nitric Oxide for Inhalation on the Development of Chronic Lung Disease in Pre-term Infants

Brief Summary

The purpose of this study is to assess the safety and efficacy of inhaled nitric oxide to reduce the risk of chronic lung disease in pre-term infants with respiratory distress, and to assess the long-term effects of the therapy on the development of these children over 7 years of clinical follow-up.

Detailed Description

Although the effects of inhaled Nitric Oxide on pulmonary vascular tone are well-described and relevant to term infants with persistent pulmonary hypertension, the pathophysiology of respiratory failure in preterm infants may be quite different. Chronic lung disease (CLD) represents the final pathway of a heterogeneous group of pulmonary disorders of infancy that usually start in the neonatal period. CLD most commonly occurs in preterm (<30 weeks of gestational age (GA) infants with birth weights less than 1,500 g, and especially in those very preterm (<26 wks GA) with birth weights less than 1,000 g, and who have been treated for respiratory distress syndrome (RDS).

Inborn preterm infants 24+0 weeks-28+6 days weeks gestational age (defined by first trimester ultrasound or if not available based on the last menstrual period) who requires the use of surfactant within 24 hours of birth (either prophylactically, or for signs of developing respiratory distress), or who requires the use of continuous positive airway pressure (CPAP) (fraction of inspired oxygen concentration (FiO2) ≥ 0.30 on a mean airway pressure ≥ 4cm water (H2O)) within 24 hours of birth in order to maintain an oxygen saturation (SpO2) ≥ 85%.
